FAQs

Question: What are the main types of binary trees?
Answer: The main types include full binary trees, complete binary trees, and balanced binary trees, each with distinct properties.

Question: How do traversal methods differ from each other?
Answer: Traversal methods differ in the order they visit nodes: in-order visits left, root, right; pre-order visits root, left, right; and post-order visits left, right, root.
